You can view this data online and it is normally the schools that take the majority of the budget, and they still don't have enough money either. I have no idea where they live but it is possible their police are in need of donations, unlike perhaps LAPD/NYPD.
Since you mentioned it, I looked it up.
The sheriff dept I donate to gets about 30% of the county budget.
The city police get just over 10% of the city budget.
